The regulations would require Zawarski to develop the land with a mix of housing, including single and multifamily dwellings, and not more than 50 percent of the development could be one type of housing.

In testimony, engineer James Birdsall said it would be unrealistic and impractical to try to develop the parcel according to the regulations because it was impossible "to lay out that type of (housing) mix" without becoming overcrowded.

He said a high structure could be used but "that does not keep with the character of the neighborhood."

In a 2-1 vote, the board granted the variance because, they decided, the size and shape of the tract and surrounding areas create unique circumstances which make this plan the best use of the land.

In other business, zoners:

- Granted a special exception to expand a lawful, non-conforming use which will allow Craig R. Snyder and Raymond R. Male to operate a business in the structure at 2709 Easton Ave.

- Delayed a decision on an appeal by Arlene Kern for a variance to construct a 10- by 19-foot addition at 1714 North Blvd. Kern was seeking a variance from setback requirements. Setback is the distance a structure must be from a property line or another structure.

- Granted an appeal by William Solivan for a variance from lot area-per- dwelling-unit requirements and to replace a lawful, non-conforming use with apartments at 700-702 William St. Solivan representative Chris Portner said the building has about 7,000 square feet and would be renovated into six, two- bedroom apartments that would be 1,200 to 1,500 square feet in size.

The building had been vacant for several years but formerly was the site of four apartments on the upper level and a grocery store on the lower level.

Portner said the interior of the building needs substantial work to be brought up to building code standards and that six apartments are needed to make the work economically feasible.

The board approved the variance because sufficient hardship had been shown and the plans would keep the building in character with the neighborhood.

- Approved an appeal of Tho Van Tran for a special exception that will allow him to use part of his home at 1556 Linden St. as a dentist's office.

- Granted a variance to William H. and Carol M. Gainer from lot area, depth, and front-, side- and rear-yard requirements that will allow them to build a one-family dwelling at 1542 Jefferson Ave.

- Granted a variance to Paul J. Mumbauer of 2331 Brown St. thatwil allow him to enclose an open patio.

- Granted a special exception to Nancy Boylston Rudzki of 1659 Millard St. that will allow her to use part of her home as an accountant's office.

- Granted a variance to Francis B. Delia that will allow him to install four efficiency apartments in a garage on Morton Street behind 110-112 E. 4th St. The variance frees him from the 12,000 square-foot lot size requirement for six apartments on one property. The lot, which already has a two-unit apartment building on it, is 7,200 square feet.
